Plastic Pipe Cross Section

Calculate plastic pipe unit mass and total mass (construction quantities) from pipe length, diameter, either wall thickness or dimension ratio, and density.

Select the pipe schedule (NPS or ISO), pipe diameter and wall thickness or dimension ratio (SDR or SIDR), or use the user defined option. The dimension ratio is calculated from the pressure design wall thickness (nominal wall thickness minus fabrication allowance and mechanical allowance). Use the Result Table option to display the pipe schedule with unit mass and total mass for the selected diameter.
